A new telecommunications course is presented that uses software-defined radios (SDR) to apply communications and digital signal processing techniques even prior to students taking those upper-level courses. At the US Air Force Academy (USAFA), Communications Theory (ECE447) and Digital Signal Processing (ECE434) must be senior-level courses, due to the amount of prerequisites. The new course, Wireless Communications (ECE448) implements modulation/demodulation and signal-processing techniques, by programming inexpensive SDRs, which do not require the advanced mathematical theoretical background. Class exercises start as MATLAB simulations that model what a “real” radio does. Then the students’ simulations actually become the programs that control the SDR hardware in real time, as students establish transmit/receive links between themselves. There is no need to understand the theory prior to implementing these techniques. Students can take this course their junior year prior to these theoretical courses, serving as a motivational tool. Or, students can take these courses after these theoretical courses, in order to apply the theory that they already learned.
